Abstract
427,306. Electromagnetic relays. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) July 19, 1933, No. 20400. Convention date, July 19, 1932. [Class 38 (v)] [See also Group XXXVI] The Specification as open to inspection under Sect. 91 contains the following. The instrument 11 may be an excess voltage relay which operates when the voltage of the winding 2 exceeds the continuous-current component derived from the battery 10, these voltages together with a blocking voltage obtained through transformer winding 6, being applied to the grid of a gasfilled discharge tube. A capacity potential divider may replace the voltage transformer 1. This subject-matter does not appear in the Specification as accepted.
